The image belongs to a work realized as site-specific by Japanese artist Motoi Yamamoto within the show «Univers’sel»where his work dialogue with the one of Jean-Pierre Formica, both engaged in realizing monumental works entirely realized with salt. The one by Yamamoto is a labyrinth. Salt is a particularly important element in the Japanese culture as much as the labyrinth is for the European culture. Salt as a media is as much ephemeral as it is technology. What changes is time and the causes of obsolescence, here also dictated by the climatic conditions where the installation is placed.
